发明名称 SEGMENTED METADATA AND INDEXES FOR STREAMED MULTIMEDIA DATA
摘要 <p>A method of organizing streamed data includes storing streamed data in a file, identifying metadata applicable to a subset of the streamed data, and forming at least one group of one or more samples of the streamed data, each sample in a group having identical metadata content for a metadata type. The file may be in accordance with ISO base media file format. The storing streamed data in a file may include storing in a reception hint track. The at least one group may be indicated in a sample group description box. The metadata type may be indicated by a grouping type and grouping instance data, the grouping type specifying semantics of the grouping instance data and the metadata content. The metadata content may comprise a metadata payload and zero or more metadata payload extensions, where the metadata payload is included in a first structure and the zero or more metadata payload extensions are included in a second structure.</p>
